q-oscillator models are considered in two and higher dimensions and their symmetries are explored. New symmetries are found for both isotropic and anisotropic cases. Applications to the spectra of triatomic molecules and superdeformed nuclei are discussed. ∗Permanent address: Saha Institute of Nuclear Physics, AF/1 Bidhannagar, Calcutta 700 064,India

As a sound source, this design uses a piezoelectric “buzzer” disk, which has a high acoustical impedance and is therefore not strongly affected by the air column’s own resonances. Buzzers with housings such as Radio Shack 273-073 or 273-064 are easy to find and have leads attached, but they must be disassembled in order to remove the brass disk with the piezoelectric element. Or, the disk itsel...
